摘 要:
根据2005年7月-10月在北太平洋150°E-158°56’E、42°34’N-46°25’N进行秋刀鱼资源探捕所获得的浮游动物样本资料的分析、鉴定，在15个站点的海洋浮游动物样本中，测得甲壳纲的桡足类、端足类、糠虾类、磷虾类，毛颚类、腔肠动物以及被囊动物等的代表种。其中桡足类占绝对优势，隶属于1目4科5属8种。总浮游生物量分布范围为136～1848mg／m^3，均值为865．6mg／m^3。[著者文摘]

Abstract:
Zooplankton, the animal form of plankton, small floating or weakly swimming animals that are transported with the water currents, includes protozoa, small crustaceans, jellyfish and worms. Zooplankton feed on phytoplankton, making them the second link in the marine food chain. Zooplankton then are eaten by krill, fish and larger crustaceans. The investigation fishing of Pacific saury （ Cololabis saira） resources was carried out in the North Pacific Ocean （150°E- 158°56＇E,42°34＇N -46°25＇N）from July to October,2005. Based on the sample analysis and identification of zooplankton samples, we have obtained representative species of Copepoda, Amphipoda, Mysidacea, Euphausiacea of Crustacea , Chaetognatha , Coelentera and Tunicata in the zooplankton samples among 15 sites. Copepoda were dominant absolutely, member of one order, four families, five clams and eight species. The quantitative distribution range of zooplankton is 136 - 1 848 mg/m^3 ,the average value is 865.6 mg/m^3.[著者文摘]
